Meeting key criteria
What then were the most important reasons for Mal-Tel’s choice? First, it was crucial that this digital radio technology could operate on 12.5kHz and 6.25kHz narrowband frequencies, making it 2 to 4 times more spectrum efficient than the current 25kHz analogue network. Another priority was sound quality, and thanks to state-of-the-art AMBE+2™ vocoder voice compression technology, NEXEDGE offers superior clarity at varying signal strengths, even in fringe areas.
There were, of course, other contenders, but for example, TETRA would require many more repeaters base stations to ensure the same coverage as NXDN, and the P25 system is considered too expensive to offer a practical trunk radio solution for the general market in Malaysia.
